Texture returned an invalid bump normal

Thank you for the quick response!

Sure. Sorry about that.

I will upload the scene later once I get back home. I did tried to replace the cellular with a noise tho, but it did not appear to make any difference.

Thanks for the solution! I will try this. It is going to affect my render times no doubt, but not by a great amount I hope.

Thank you once again,
Zdravko
